Application filed .Tune 10,

This invention relates to bedspring stay devices of the type designed to brace the border rods or wires against the objectionable lateral swaying of the springs upon their base. It is an object of my invention to apply a pivoted link mechanism to a bed spring made up of a series of coiled springs and more especially to such springs of the double-deck type, though the mechanism may well be used for bracing coiled springs of the single-deck type, as will be readily understood.

It is my purpose in providing my improved stay device to mount the same upon a base having elements extending in a direction at right angles to the length of the.

bedspring and also in a direction parallel to the side border wires, so that my improvement will serve to brace the springs to some extent lengthwise of the bed as well. as laterally. To do this I provide base connections with certain side bars of the springs and also with cross bars thereof. It is a further object of my improved device to mount. the

' same upon a horizontal base, or one that is in the plane of the bedspring bottom.

It is a particular object of my device that the said mechanism when in operation shall not resist vertical movement of the springs or of the border wire attached thereto, but will be effective in resisting lateral movement of the springs relative to the bedspring base. It is a further object of my improved device to provide an efi'ectii e bedspring stay device that may be readily mounted upon bedsprings whose side bars may not be mounted on a plane substantially lower than the bottom of the coils, as well as those having the coils lowered below the plane of the sidebars.

With these and other objects of my inven tion that will appear as the description proceeds, I have embodied my inventive idea in the structure and combination of parts hereinafter fully described recited in the appended claims, and illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of the device shown as a unit detached from any frame;

Figure 2 1s a slde elevation of the device mounted upon a bedspring adjacent the side bar and attached. tothe border wire which is shown 1n sect1on; and

gether with four adjacent spring coils and showing certain connected parts in section.

I have shown my improved. device applied to a bedspring having doubledeck coils 5 supported upon cross bars 6 which are usually mounted in edge-wise position in the frame of the bedspring, and upon certain wide and stronger cross bars 7 which are often used intermediate the ends of the sprlng where the weight and consequent strain is apt to be greatest. The upper-ends of the coils 5 may be cross braced by coil springs 8 by plain wire, or by cable connections, if desired. Intermediate straps or wires 9 may brace the intermediate portions of the coils 5.

Theside bar 10 of angle iron is shown as affording support for the outer row of coils, and has attached thereto ends of the cross braces 6 and 7, as well as serving for attachment of my stay device. About the outer rows of spring coils 5, the border wire or rod 11 extends, and is attached to the upper spiral of each coil independently, usually by means of a wire strand 12 encircling the strand and rod. Intermediate a pair of outer coils my stay device is usually mounted, and includes a relatively long locked lever 13 whose outer end is secured. to the border rod 11 by suitable attaching means, such as a loop 14 surrounding the rod and having outwardly bent ears 15 receiving therebetween the outer end 16 of the lock lever, the latter and the said ears being riveted or bolted together. i My stay device is preferably mounted upon a T-base formed of strap iron bars 17 and 18, the former extending in the direction of the length of the bedspring and having. its ends 1.9 bent inwardly into parallelism for suitable attachment to cross bar 6 or to the cross bar 6 and one of the stronger bars 7. The strap 18 has its ends bent at right angles'to the main portion, one of them 20being riveted or otherwise secured to an intermediate portion ol strap 17 and tl1e pposite end 21 secured directly to the side bar 10. The

cross bars 7 may be formed of angle iron and so positioned that its uppermost arm, as well. as that of. the side bar 10 shall be horizontal, the arm 22 serving to support there on theouter row of coils 5, and receiving there-under the outer ends of the bars 6 and 7 and the bent ends 21 being riveted to the vertical arm 23.

; pivot.- At a point nearer the end 21, is securely mounted upon strap 18 a standard 26=fixed to said strap and in a position substantially at right angles to 18 and extending towards the lever 13. The outer end of the link- 24 is pivoted at 27 to the inner ,eIid of the lever 13, and the outer end of link is pivoted at'2'8 to an end of a link 29 whose opposite end is pivoted tothe lever 13 at V 30, a point somewhat remote from pivot '27. 4

"The outer end of the standard 26 has pivo'ted thereto an end of a link 31 whose op- "po'sit end is pivoted at 32 to an. intermediate point of link 29. This pivot 32 is'or- 'dinarily somewhat nearerthe pivot than the point 28 but this position may be' changed depending upon the heightrofthe coils used in the bedspring to which my imvided It is obvious that the length of 'par'ts :26 and 31 may be varied to adjust proved device is applied, and upon lengths of'the-links with which the leveris protheheight which the border rod 11 is intended to assume in its higher and lower pojjsitions, and the said variation is contem- 1 plated.

; 'IThe arrangement of the parts described above provides movement of the end 16' of lever 13 toward, and away from the pivot 36; "that the links 24, 25 and 29 with the i inner end of the leveriorm in effect a lazy- ..f tphg's" device for said movement. The entire device comprising parts 13, 24, 25, 29

not only is adapted to move toward and ,away from36, but also may swing as a unit upon said pivot 36, unless other means is provided for controlling such movement.

For 7 the latter purpose the link v31 directs the lazy-tongs in such swinging movement,

so that the loop 14 is controlled and limited to a substantially "vertical direction when the bedspring is in operative position, but is prevented from a lateral movement, so that the: borderwire ll and the springs attached thereto are locked against the undesirable I swaying movement of the upper portion of the springs.

" In additiq fte'the control afforded by the impmved tay device so far described, I provide b ...a "1i arrangement ofparts disclosed, for the verticakmovement of the looip; e foritsfextreme upper position and lowest position, so that the bedspring may 'belift'ed'by meansofthe border wire without straining the coiled springs, and no injury will be done to the bedsprin by compressing the upper frames thereo for shipment. For this purpose, it will be noted that the lever 13 will strike the upper end 35 of the standard 26 when the lever lowers to its lowest position, contacting 35 at about the point a. On the o3posite movement to the upper limit, the point 1 of the lever 13 will contact the end 34 of link 31, and thereby lock the device against further upward movement. It is to be understood that the standard 26 is fixedly secured by rivets 33 to the base member 18.

My improved stay device is rendered very stable b the base 17l8 which is securely attache to the bars of the lower frame of the bedspring, and thereby affords strong and efiicient support for the pivoted stay members. It is also adapted to mounting upon bedsprings whose bars 10, 6 and 7, are in a common plane, as well as the form of structure inwvhich bar 10 is on a higher plane than 6 and 7. It is evident that my device may be readily applied to other forms of .bedsprings than that here illustrated, it being only essential that the beds )rings shall be provided with a series 0 coil springs and a border wire about the upper ends of the outer row of springs, a suitable base or foundation for the springs and this device being, of course, necessary. The T-base is found to be especially desirable, but the stay device may evidently be mounted upon other base structure.

Other details of my improved device may be modified without departing from the inventive ideaof the same.

Having disclosed an illustrative embodiment of my invention, what I claim and desire to secure b Letters Patent is,--

.1. In a bedspring, the combination of a bottom support for a series of coiled springs, a border wire connected to the upper ends of said springs, a lock lever nected at its outer end to sai border wire, alazy-tongs device comprising three links and an inner portion of said lever, pivoted to said support and serving to extend the lever away from and towards the support, and means connected to the su port at a point remote from the pivot o the lazytongs, and to the latter, to limit and control the movement of the lever.

2. In a bedspring, the combination of a.

bottom support for a series of coiled springs,

a border wire connected to the upper ends of said springs, a lever connected at its outer end to said border wire three links and an inner portion of the lever comprisin a lazytongs device pivotally connecting the inner end of the lever to the support and serving to extend the lever away from and toward the support, a standard secured to the sup port remote from said pivotal connection, and a link pivotally connecting the upper tpivotally con-V end of the said standard and the said lazytongs.

3. In a bedspring, the combination of a bottom support for a series of coiled wire springs, said support including a T-base, a lock lever having its outer end pivoted to the border wire of the bedspring, link mechanism pivotally connecting spaced points of the said lever to a single point of the said T-base, and link means pivotally connecting the said base with said mechanism, for limiting the movement of the latter on said single point of the T-base.

4. In a bedspring the combination of a bottom support for a series .of coiled springs, a pair of upstanding and downwardly-converging links pivotally connected to a unitary point on said support, a part pivotally connected to the upper end of one of said links and having an outwardly-extending portion, a border wire connected to the upper ends of said springs and to said extending portion, a third link connecting the outer end of the other of said upstanding links and a point of said part remote from its connection with the first said link, and means for limiting the lateral swinging of the device on its unitary pivot transverse oi' the bedsprin 5. In a bedspring, the combination of a bottom support for a series of coiled Wire springs, said support including a base member of T-form, a lock lever having its outer end pivoted to the border wire of the bed spring, a pair of upstanding links pivot-ally united at their lower ends at a common point on said base member, one of said upstanding links being pivoted to the inner end of the lever, another link pivotally connecting said lever at a point spaced from its end with the outer end of the other upstanding link, and means connected with said pivotally connecting link for limiting the rearward movement of said links and the lever carried thereby.

6. In a bedspring, the combination of a bottom support for rows of springs and ineluding a T base, a pair of upstanding links pivotally connected at a common point on the main element of the T, a lock lever having its outer end pivoted to the border wire of the outer row of springs, a connecting link pivoted at its ends to the outer end of one of said upstanding links and to an intermediate point of said lever, respectively, and the outer upstanding link pivoted directly to the inner end of the lever, both upstanding links being mounted on the same side of the lever and main element, a standard fixedly secured to said main element of the base, and means pivotally connecting the outer end of said standard to an intermediate point on said connecting link, whereby the border wire will be limited in its upper movement by the lever striking the pivotally connecting means adjacent its point of attachment with the connecting link, and will be limited in its downward movement by striking the upper end of the standard.

In witness whereof I have hereunto set my hand this 8th day of June, 1926.
